PENNSYLVANIA, A CQRBORA- Application filed August 25, 1931.- sriarNo. 559,2?4?

This invention is a lock for application to metallic doors and has for its object the provision of a construction which will facilitate the installation of the lock and will'provide for the firm securing of the lock in place without detracting from the appearance of the door. Another object of the invention is to provide simple and eflicient means for preventing excessive strain upon the hub or other moving part of the lock. Other objects of the invention will appear incidentallyin the course of the following description, and the invention resides in certain novel features which will be particularly pointed out in the I appended claims. 7

In the accompanying drawing,

Figure 1 is an elevatlon, partly broken away, of a portion of a door havlng a lock 7 embodying my improvements applied there- Fig. 2 is an edge view of the same, partlybroken away and in section,

Fig. 3 is a view showing the lock in top fplan and the door in horizontal section,

Fig. 4 is a detail perspective View of the escutcheon and spindle of the lock.

In the drawing, the reference numeral 1 indicates a portion of a metallic door which may be of any embodies a substantially rectangular stile, illustrated in the drawing. Alined axially in the opposite sides of the stile of the door are openings 2 which receive the spindle 3 of the lock, and the mechanism of the lock, which may be of any :known or approved type, is contained within a lock case 4 which is secured within the stile of the door, as will he understood. The lock case includes a face plate '5' which is adapted to seat within a slot or opening provided-therefor in the edge of the door and of the same contour as the face plate. The face plate is provided at its threaded and adapted to receive a screw 7 approved detailed design and inserted through an opening providedtherefor 111 the edge .of the door whereby to secure the lock in' place, as will be understood upon reference to'Fig. It will be noted that the screws 7. arev "provided with heads having beveled edges, and the opening provided in the door is correspondingly beveled,:so that the latch bolt 8 isretracted by rocking the spindle- 3, being spring-projected in the usual.

' manner. The lock is also provided with a locking, key-controlled bolt 9, but,-as these.

parts are well-known, further reference thereto, is deemed unnecessary. The, spindle 8 1nay be of the through, split, swivel, or other-known or approved type and is noncircular in cross section so that, when it is rocked, movementwill be imparted to the p artsengaged-therewith, and the bolt will be operated. The ends of thespindle project whenthe screw'is'turned home'the face plate from the oppositesides of the lock case and I through the openings 2 in the. door and have secured upon their extremities handles 10.

which may be of any convenient form and will be usually given'amorxor less ornamental appearance. Each handle has'a hub portion 11 which rests within a recess or seat provided therefor in aboss on the outer side of an escutcheon 12, asrshown clearly in Fig. 3. Each escutcheon is also provided in its inner face with a recess'13'of circular outline, and provided at diametrically. opposite points with inwardly extending stop lugs 14, and thespindle is provided with cooperating stops which may be in the form of. a.

collar or: plate 15 having agenerally circular contour and having diametrically opposite lugs 16 on its periphery which areada-pted to impinge against either stop lug 14 and thereby limit the movement of the spindle. Theparts are asSembledinsuch relation that when the latch bolt Swis fully retracted or fully projected, thelugs 16 will impinge against the lugs land thereby preventfurther rocking of the spindle: and, consequent- 1y, will prevent breaking strain being imposed upon any of the parts of the lock.

plates 15 slipped over the ends of the spin dles, and the spindles then inserted into thehub of the lock. Each escutcheon is provided on its inner face, adjacent its lower end, with a boss, one escutcheon having an opening therethrough alining with the bore of the boss 19 thereon while the boss 20 on the other escutche on forms an internally threaded socket, and. at the upper end of each escutcheonis an opening 21 provided to receive' ascrew 22 which has threaded engagement with the stile of the door whereby the escutcheon will be secured in place. The ength of the escutcheons is such that the bosses 19 and 20 clear the lower end of the lock case and a through bolt 23 is inserted through the boss 19 and engaged in the boss 20 to fasten the partstogether and in place.

The door may have beads or molding 17 supportinga panel 18 of glass or other material.

The handles are secured to the spindles in any well known or approved manner, my usual practice being to cast each half spindle in a handle.

It will be readily noted that the device is very simple and compact and may be readily fitted within the door and, when in place, will be firmly secured without detracting from the appearance of the door. 7 7 Having thus described the invention, I claim:

1'. In a lock, a spindle of non-circular cross section, an escutcheon providing a bearing for the spindle and having a recess in its inner face concentric with the spindle and provided with inwardly projecting diametrically opposite lugs on its wall, and a plate fitted on the spindle and adapted to fit within said recess and "provided with diametrically opposite projecting lugs on its periphery to engage the lugs in the recess and limit'the movement of the spindle.

2. In a look, a spindle of non-circular cross section, escutcheons having openings therein for the reception of the adjacent ends of the spindle and provided on their outer faces with bosses having seats formed therein constituting bearings, handles secured to the spindle and provided with hubs journaled in said bearings, there being recesses in the inner faces of the escutcheons concentric with the spindle and having their walls JOHN V.
